Specification of Letters Patent.

Patented Aug. 19,1913.

Application filed September 16, 1907. Serial No. 393,196.

To all whom it may concern lie it known that we, DANIEL N. PRIME andEnnns'r rrsirron, citizens of the United States, residing at Lynn andSwampscott, respectively, in the county of and Commonwealth oflidassachusetts, have invented certain Improvements in Presses, of whichthe following description, in connection. with the accompanyingdrawings, is a specification, like reference cluiracters on the drawingsindicating like parts in the several figures.

[if his invention relates to presses and while many features of theinvention are applicable to presses in general which may be used formany purposes, the invention is herein, for the purpose of explanation,shown as embodied in a press adapted for use in dieing-out sheetmaterial.

in important feature of the invention consists in providing a pluralityof means for relatively moving the cooperating pressure applying membersof the press, which means is so constructed and arranged that the degreeof pressure applied may be controlled. Preferably and as herein shown,the arrangement is such that the operator can render one or another ofsaid actuating means operative or render a plurality of them operativeat the same time to cause pressure to be applied. in practice the powerrequired to be applied by a press \"ar' according to the work to be doneat a particular operation. For example, in a dieing-out machine theforce with which be actuated varies with the size of the dies, the kindof stock, and the thickness of the stock. No advantage is gained by theuse of force greatly in excess of that needed and disadvantagessometimes result in addition to the waste of power. in accordance withthe illustrated embodiment of this feature of "the invention theoperator, having in mind the particular work in the machine, enabled instarting the machine to select or to control the operating mechanism.according to the force required. As shown, a plurality of operatingmechanisms adapted to apply different forces are so arranged that eitherone or another may be started alone for operating the machine, or aplurality of them may be started. to act together. Preferably theoperating mechanisms employed will be fluid-actuated motors which areherein shown as two cylinders of different diameters bot-h connected to.the movable pressure-applying member and arranged so that either canoperate alone or both can work together. By this arrangement threedifferent pressures may be obtained. The motors are controlled byseparate starting means which extend into convenient position for theoperator to engage them and are arranged so that both can be actuated atthe same time when desired. The fluid-operated motors have the advantagethat a predetermined force, dependent upon the fluid pressure and thesize of the cylinder, may be obtained and applied to the workindependent of thickness of the work or the height of the dies.

An important feature of the invention consists in a construction of themeans for supporting the presser block or platen whereby the presserblock may be brought into operative position over a movable die whereverlocated on the bed and wherein provision is preferably made for movementof the presser block over the bed in different directions. Preferably,and as herein shown, the means for supporting the presser block, or thepresser block carrier, is in the form of a radial arm which is arrangedto swing over the bed in a plane parallel there with. The swingingcarrier will, for convenience, be herein frequently referred to as aradial arm. This term is used, however, for the purpose ofidentification and is not to be understood as implying a limitation.Preferably also provision will be made for a radial movement of thepresser block with respect to the axis about which the swinging carriermoves, so that by a combination of the swinging and radial movements thepresser block may be positioned over any part of the working area of thebed within the sweep of the radial arm. The provision of aconstructionin which the presser block or platen is arranged for both angular andradial movement over the bed is especially important when, as hereinshown, the dimensions of the pressure face of the presser block are lessthan the corresponding dimensions of the bed and the ma chine is to beused with a die which is freely movable over the bed.

Another feature of the invention consists in the arrangement of themechanism for controlling the motors. The presser block, which ismovable lengthwise of the radial arm, is provided with a handle by meansof which it is shifted upon the arm and by means of which the arm isshifted over the table. The devices for controlling the motors includetriggers or finger-operated members arranged upon the presser block andin such relation to the handle that they may be manipulated by thefingers of the hand which grasps the handle. By this arrangement theoperator may with one hand-as, for example, his left hand-position thepresser block over the desired portion of the work and then start themotors with the fingers of the same hand. This arrangement allows theoperator to have his other hand free for manipulating the work or thedie in case a movable die is employed. A valuable feature of thisconstruction is found in a movable connection which is provided betweenthe finger-operated members and the other portions of the motorcontrolling devices, whereby said devices may be actuated while thepresser and the fingeroperated members occupy different relations to theother portions of the connections. As shown, the finger-operated devicesinclude crank arms which move with the presser block and are slidinglyconnected with shafts carried by the radial arm.

In the use of the machine for such work as cutting shoe upper stock, forexample, in which it is desirable to out different parts of the upperfrom portions of the stock diftering in qualities, it is desirable thatthe operator may have unobstructed light upon the stock lying upon theworking area of the bed, or the portion within the range of the presserblock, in order that he may judge of the quality of different portionsof the leather. Having this condition in mind the present machine hasbeen arranged as above described with the presser block carrier in theform of a radial arm mounted to swing over the cutting bed in order thatthe light upon the work shall be obstructed as little as may be. Alsowith this object in mind the post upon which the radial arm is mountedis arranged at one side of the bed and preferably at the rear left-handcorner of the bed, or the rear left-hand corner of the working area ofthe bed which the radial. arm is intended to cover. Preferably themachine will be set up with the back and right-hand end of the tabletoward the light. These provisions for obtaining unobstructed light uponthe work are believed to be valuable characteristics of the invention.

For the purpose of extending the size of the cutting bed to take largesides of leather without providing a radial arm of too great length forconvenience or necessitating the use of a portion of the bed upon whichthe light will be obstructed by the post and the radial arm the bed isarranged for movement to present a plurality of working areas thereof inthe described relation to the post. Preferably and as herein shown,means,

'which is adapted to be rendered operative by the workman, is providedfor effecting the movement of the bed from one working position towardanother. As herein shown, this means comprises a fluid-operated motorwhich is controlled by a lever which is to be shifted to one side of acentral position for starting the motor to move the bed in one directionand to be shifted to the other side for reversely moving the bed.Provision is made for automatically checking and then stopping the tableat the end of its traverse in case the operator neglects to do so. Tothis end a stop is arranged to offer a progressively increasingresistance to the ad vance of the bed as it approaches the end of itsway. This stop is operatively connected with the controlling lever andas the bed reaches the limit of its traverse the stop automaticallyshifts the lever to stop the motor. A spring is arranged to hold thecontrolling lever normally in its central position, but in the eventthat the momentum of the bed causes the stop to throw the lever beyondits neutral position and starts the motor for moving the bed in thereverse direction, the spring immediately centers the lever again andstops the motor. The provisions described by which the bed is arrangedfor movement to present different working areas at different times andby which the bed is actuated as described constitute useful features ofthe invention.

Another feature of the invention consists in a novel arrangement of stopdevices for checking the swinging movement of the radial arm. In theillustrated construction the arm is provided with stop shoulders betweenwhich extends one arm of a pivoted bar, the shoulders being spaced farenough apart to allow for the angle of movementthat. the radial arm isto have. The rear end of the pivoted bar is positioned between twospring buffers which are shown as spring-pressed plungers havinginclined heads. Beyond these yielding buffers are arranged rigid stopswhich positively check the movement of the radial arm in case themomentum of the arm carries it over the buffers.

It is contemplated that in the use of the machine for dieingout stock adull or blunt-edged die will be used to out the stock and with this diewill be employed a bed having a hard metal face, the term hard. metalbeing used to distinguish from such metal as lead, which would beindented and roughened by the pressure applied to the die in cutting thestock. The die may be a double-edged, reversible die, as shown in thedrawings, and the presser block will in that case preferably be providedwith a hard metal face to engage the upper edge of the die for forcingthe die through the stock supported by the cutting bed. This die is notherein specifically claimed nor is any claim made in this application tothe combination of a blunt-edged, reversible die with a cutting bed anda presser block having hard metal faces for engaging the die in thecutting operation. This subject-matter is covered by anotherapplication, Serial No. 393,195, filed Sept. 16, 1907, for LettersPatent for improvements in cutting apparatus.

These and other features of the invention, including certain details ofconstruction and combinations of parts, will be hereinafter describedand pointed out in the claims.

Referring to the accompanying drawings which represent a preferred formof our inventionl igure 1 is a side elevation; Fig. 2 is a frontelevation; Fig. 3 is a broken, vertical section through the pistons andcylinders for actuating the radial arm, taken on the line 33 of Fig. 2;Fig. 4: is a perspective view of the connections between the triggersand the valves actuated thereby; Fig. 5 is a plan view showing themechanism for operating the cutting table, the radial arm beingindicated in broken lines; Fig. 6 is a perspective view of a die of thetype hereinabove referred to. I

The base or frame 2 of the machine, which is designed to rest upon thefloor, supports a table or bed 3, which may be of any suitableconstruction, but which will preferably be formed as hereinafter moreparticularly described. Rising from the base are upright arms 4, a whichare joined at their upper ends to a bearing 5 in vertical alinement witha bearing formed at 6 in the base. In these hearings is arranged ahollow shaft 8 and between collars 10 on that shaft is mounted to turnthe hub 12 from which projects radially an arm 15, herein referred to asthe radial arm. This arm carries the member which cooperates with thebed for applying pressure to the stock interposed between said parts, orto a die 21 which is located upon the stock, and this member is shown asa presser block 10 having a contact plate 18 securedto its lower face at20 for universal tipping movement. This connection permits the contactplate to adjust itself automatically into parallelism with the cuttingbed or into such other position as the interposed stock or dies mayrequire.

As hercinabove suggested the die used with this machine may be a doubleedged reversible die, as shown especially in Fig. 6 of the drawings,this die being described more fully in the'co-pending application ofDaniel N. Prime, Serial No. 393,195, filed Sept. 16, 1907. The presserblock is shown as connected with the ""adial arm for movement lengthwisethereof and is formed with guides to engage ribs 22 formed on the sidesof the arm. The sides of the presser block extend upwardly above theribs as appears in Fig. 2 and are formed with a runway to receive aseries of balls or rollers, as shown in Fig. 1, upon which the weight ofthe block rests when the block is not in contact with the work. Thisconstruction renders the block easily movable on the ra dial arm foradjusting it into different positions over the bed.

The radial arm and the presser block are actuated vertically forapplying pressure to work upon the bed by endwise movement of the shaft8. This shaft forms or is operatively connected with the piston rod of afluid-operated motor which comprises the cylinder 25 in which works thepiston head 26. A valve rod is movable endwise in the cylinder head andis arranged to act during its stroke to the left, see Fig. 3, closingthe exhaust port 32 and then opening the inlet 3% to which air underpressure is supplied from the pipe 37. This rod is formed at one endwith rack teeth which are engaged by teeth on the upper end of a shaftThe shaft is also toothed at its lower portion and is engaged by rackteeth. on a slide rod 36 that is connected by a bell crank 38 with a rod410 that extends up wardly through the cylinder and the hollow shaft orpiston rod 8. The upper headed end of this rod is engaged by the forkedend of a lever -12 which is mounted on a post rising from the radial arm15. This lever is connected at its outer end by a link 43 with a crankor arm 4st on a rod 15, which is mounted in the radial arm 15 andextends through bearings or bosses which are formed on the upper side ofthe presser block 16 and extend into a length wise recess in the lowerface of the arm. This rod is provided with a keyway 18 in which isfitted to slide a key carried by the hub of a crank arm that isconnected to the vertically movable rod 59 which is guided in thepresser block 16. The rod 59 has a stud 54 that is engaged by an inclineon the lower face of a trigger or slide 55 which is normally held by aspring 53 with the low part of the incline against the stud. The triggerhas a finger piece which is located adjacent to the handle 59 of thepresser block in such position that the operator may pull the triggerwith a. finger of the hand that grasps the handle 59. By thus pullingthe trigger outwardly, after having positioned the presser block bymoving it with the radial. arm and relatively to said arm into the rightplace over the table,

&

motion will be communicated through the described connections to thevalve rod 30 to admit air under pressure to the cylinder 25 and actuatethe presser block downwardly.

Below the cylinder 25 is a second cylinder 61 having a piston head 63which is also attached to the rod or stem 8. The cylinder 61 is smallerthan the cylinder 25 and adapted to actuate the presser block with asmaller force suited to easier worl. This cylinder is provided with avalve rod 65 controlling the inlet and exhaust openings 67 and 6t) andis actuated by a set of connections 59, 60, 62 6 1, 66, 68, 70, 72, 7 1,76, 78, 80, and 82 with a trigger 8 1 acted upon by a spring 83 andmounted beside the trigger 55 in position to be engaged instead of thetrigger 55, or in addition to that trigger in case it is desired to useboth cylinders at the same time.

The cylinders 25 and 61 are one-way cylinders open at the bottom and thepiston heads for the two motors are attached directly to the same stem,which is the post 8. Below the piston head 63 and acting against it aresprings 85 that raise the piston heads and the motor-actuated parts whenthe trigger or triggers are released to permit the exhaust ports to beopened by the springs 86 acting on the valve rods 30 and 65. The hollowshaft 8 is mounted at the rear left corner of the base or frame 2 andthe cutting bed 3 is mounted in front thereof, as indicated in Fig. 5.The radial arm 15 which is mounted on said shaft 8 is adapted to swingover the bed 3 between the two positions indicated in broken lines onFig. 5.

The hub 12 of the radial arm has on its rear side shoulders 90 betweenwhich is located one end of a pivoted bar 92, the other end of which hasinclined lower side faces which normally rest between spring-pressedplungers 9a. The bar and the plungers act as yielding buffing means tocheck the swinging movement of the arm. Rigid stops are providedateither side of the plungers to arrest the movement of the barpositively if the momentum of the arm should carry the bar over theplungers.

The cutting bed 3 is approximately rectangular in outline and may beprovided with a cutting surface, as by mounting plates 100 of a hardmetal upon a supporting plate 102. The bed is so mounted on the base orframe 2 as to slide longitudinally thereof, having ways 104. which coact with guides 106 formed on the base or frame. Any convenient meansmay be provided for actuating the bed, but in the form illustrated lugs108 are mounted on the lower side of ti e bed and carry a piston rod110, having a piston 112 within a stationary cylinder 114;, preferablymounted on the frame of the machine. Means is provided for admittingfluid under pressure at will to either end of the cylinder to move thepiston in either direction. On each end of cylinder 111 is supported avalve casing 116 Within which are located inlet and exhaust valves 118and 120. The stems for these valves extend without the casing and arepivotally connected to levers 1.22, which in turn are connected by alink 12 1. One of the levers 122 is extended through an opening 126formed in the base or frame 2 to provide a'handlc 127 to be grasped bythe operator. The stems for the inlet valves 118 and 120 are arranged inaxial alinement and between them is mounted a spring 128 to hold saidvalves closed. Bell-crank levers 130 are mounted on the frame of themachine adjacent to each end of the cylinder, and corresponding arms ofsaid levers are connected by a link 132 which is also connected to oneof the levers 122. The other arms of said levers 130 are extended in theform of cams with which co-act rollers 13 1 mounted on the ends of rods136 adjustably secured to the lower surface of the cutting bed.

In the operation of this machine the Work to be operated upon issupported on bed In case stock is to be died out the die is then placedin proper position on such stock. When the cutting bed is provided witha hard metal surface a cutting die having a dull or blunt edge willpreferably be used. The presser block 16 is then brought into properposition to act upon the desired portion of the workas, for instance, byengaging the upper edge of a die already positioned on the stock toforce the cutting edge thereof through the stock. By swing ing theradial arm angularly on its supporting shaft 8 and moving the presserblock 16 by means of the handle 59 lengthwise thereon the contact plate18 may be brought over any part of the bed 3 within the limits of thatsector of a circle the center of which is on the axis of the shaft 8 theradius of which is equal to the effective length of the radial arm 15and the angle of which is determined by the position of lugs orshoulders 90 on the hub 12.

Having brought the presser block 16 into position and while stillholding the handle 59 the operator reaches with his fingers to pulloutward on trigger 55 or trigger 8 1, or

both, according to the amount of pressure it is desired to exert. Themovement of the triggers is transmitted through the connections abovedescribed to the valves controlling the supply of fluid under pressureto the motors, admitting fluid to one or the other or both of saidmotors, and depressing the radial arm 15 and presser block 16 carriedthereby to force the die through the stock. o have shown motors whichare actuated in one direction only by fluid pressure, being returned bysprings; but we do not desire to be limited thereto as two-way motorscould be employed equally well. l/Vhen the operator releases thetriggers they are immediately returned to inactive position by springs53 and 83 permitting the springs 86 to close the inlet valves to thecylinders and to open the exhaust, when the pistons together with thepiston rod 8 and the radial arm 15 are elevated by the springs 85,enabling the operator to remove the piece cut out and to position thedie anew. Then as many pieces as possible or desirable have been stampedfrom that area of the hide which is within reach of the presser blockfor any position of the cutting bed the operator grasps handle 127 andmoves it in the direction in which it is desired to move said bed. Itthe bed is in the position shown in Fig. 5 and it is desired to move thetable to the left, the operator moves the handle 127 toward the left,causing the lever 122 situated at the right of the cylinder 114 totulcrum on the stem for the inlet valve 118, which is held from movingby the spring 128, and to close the exhaust valve 120. The stem for theexhaust valve 120 thus becomes the fulcrum for the lever 122 and in thefurther movement of said lever the inlet valve 120 is opened against thetension of spring 128, admitting the actuating fluid to the right of thepiston to move said piston and the cutting bed 3 toward the left. At thesame time motion is transmitted through the link 12 1: and the lever 122at the left of the cylinder 11 1 to open the exhaust at that end topermit the cylinder to be moved. When the operator releases the handle127 the inlet valve is closed by the spring 128, holding the piston andcutting bed in the position in which they are situated at the time.Should the operator neglect to stop the table at the pro-per time one ofthe rollers 134: mounted on the rod 136 will contact with the camsurface of its corresponding bell-crank lever 130 and cause said leverto rock and to return the lever 127 to inoperative position through link132. Should the momentum of the bed 3, however, be too great to beimmediately checked by cutting oif its power, the bell-crank lever 130will be rocked farther by the continued movement of its rod 136 and thehandle 127 and lever 122 will be moved past inoperative position toadmit the actuating fluid to the other end of the cylinder and reversethe movement of the piston. This movement of the piston in the reversedirection is but slight, however, for the handle 127 is moved toinoperative position by the spring 128 as soon as the bell-crank lever130 is released by the reversal of the movenent of the rod 136.
